JOHN FARREL, OF NEYV YORK, N. Y.

SAFE.

SPECIFICATION forming part of Letters Patent No. 453,181, dated June 2, 1891. Application filed September 15, 1890. Serial No. 364,950. (No model.)

To all whom it may concern.-

, vented certain new and useful Improvements in Safes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon,whioh form part of this specification.

My invention relates to an improvement in construction of safes.

In the drawings which accompany and form part of this specification, and in which similar letters and figures of reference refer to like parts in the several figures, Figure 1 shows a horizontal cross-section of asafe having my improvement. Fig.2 shows a portion of the layers or plates of the door. Fig. 3 shows a modified form of construction.

Referring more specifically to the referencenumerals marked on the drawings, lindicates the body of the safe, to which door 2 may be hinged at 3 or secured in any other Well-known manner.

My improvement consists more particularly in the construction of door, and, as shown in Figs. 1 and 2, consists in providing a frame for the door, (indicated by 4,) which isa square or rectangular frame having an inwardlyturning flange 5, surrounding the door, and having a rabbeted edge (indicated at G) to receive from the outside panel 7, which is secured in place by the screws 8, passing through the next inner layer or plate and engaging in the panel. The flange 5 forms a double offset to engage against the jambthat is, offset 9 is adapted to engage against the body of the safe and ofiset 10 is adapted to engage against the packing 11,surrounding the jamb of the door. The layer 12 of the door fits into the surrounding flange 5, so that the flange acts as a frame for the layer 12 on the door 13, 14:, 15, and 16 indicate other'layers of the door, each of which is provided with a surrounding flange, formed integral therewith, each of which flanges, excepting 16, act as a frame to receive the next inner plate or layer of the door. These plates orlayers are secured the flange forming a frame for the same and retaining it in position. 19, 20, 21, and 22 are layers or plates having inwardly turning flanges, the edge of which flange forms an offset on the periphery of the door In the construction shown in Fig. 1 of the double ofiset 9 and 10 of the inwardly-turning flange 5 part 9 shuts by the bottom of the offset on which the packing 11 is mounted. It will be observed that the jamb is provided,

instead of one of its regular offsets, with a tongue 23, which engages in a corresponding groove in the door, and thus the regular succession of offsets on the jamb and layer on the door is broken by having the said tongue and groove.

24 indicates a packing on the face of one of the offsets on the jamb.

Of late it has become the practice among safe-breakers to cut off an edge or corner of the plates or layers of which a safe-door is formed and insert liquid explosives, which, when exploded, separate the plates of which the door is formed or injure the door, so that it may be opened. In case the plates are merelyseparated theplateloosened is removed and the same proceeding taken with each successive plate until the door is fully opened. It is with a view of preventing this practice that my invention largely tends. With a door formed of successive layers, with flanges formed integral therewith, as before described, great strength is obtained at the point where heretofore weaknesses have been found, and in forming a door, as heretofore described, having a panel and a door-frame formed with a flange, as described, many advantages in strength and construction are gained. It will Of course it will be understood that I do not necessarily form a safedoor of its entire thickness of plates or layers compiled in this manner, but it is within the spirit of my invention where two or more layers are provided, one or more of which layers have a flange formed integral therewith, which receives its next layer.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, in asafehavinga doorjamb adapted to receive the door within the jamb and receding by steps from the front, of a door adapted to enter the jamb, composed of layers or plates having inwardly-turning flanges formed integral therewith and forming a frame for one or more of the inner layers or plates, and the flange-face forming an offset on the door, substantially as set forth.

2. The combination, in asafe having a d00r-' jamb adapted to receive and surround the door and receding by steps or offsets and tapering inward, of a door adapted to enter the jamb, having its outer wall formed of a plate or frame having inwardly turning flange formed integral therewith and forming a frame for the innerlayer of the door, the transverse face of said flange forming a double receding offset, substantially as set forth.

The combination, in a safe having a doorjamb adapted to surround the door formed with steps or offsets, of a door composed of two or more plates or layers having right-angular integral flanges extending inward beyond the plane of the inner face of the plate, forming offsets, the flange of one of the plates also engaging between a projecting flange on one of the steps or offsets of the jamb and the body of the jamb, substantially as set forth.

4. A safe-door havinga frame formed of angle-iron, a panel rabbeted into the frame from the outside and secured by screws passing through the next near plate and into the flange and panel, substantially as set forth.

In witness whereof I have affixed my signature in presence of two witnesses.
